Reported my phone on the 20 Nov 2017 online ref no 680CRK201117. I have phoned them twice received an escalation no ********** nothing happens. Phoned them again answer is a technician is allocated to you. I check on faults every day no progress since 20 Nov 2017. I used there chat facility explained to them on three different occasions I need my phone for business purposes the only answer I got is a technician is allocated to your problem.
